Biomass production, arbuscular mycorrhizae and soil plant-available P under water stress in native perennial grasses
(CRC Press-Taylor & Francis, 2010-10)Precipitation determines vegetation type and species relative composition in plant communities [1]; in addition, it is a primary variable affecting soil water storage and availability. This availability is the most important ... -
Caracterización de entradas de Gossypium hirsutum L. a través de variables asociadas al uso del agua
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2016)El estrés hídrico limita la productividad de los cultivos, unas de las estrategias para minimizar el impacto producido es la selección de variedades agronómicamente más eficientes en la utilización del agua. En el ... -
Effect of water stress in Megathyrsus maximus during vegetative growth and early selection of promising genotypes
(Sociedad Argentina de Fisiología Vegetal, 2023-10)Megathyrsus maximus is a cultivated forage grass in tropical and subtropical regions of the world. In Argentina it is widely used in livestock systems due to its high production and forage quality. However, climatic ... -
Fenotipado y genotipado con marcadores SSR de líneas endocriadas de girasol (Helianthus annuus L.), contrastantes para la tolerancia al estrés hìdrico
(2019-03-21)El girasol (Helianthus annuus var. macrocarpus) es el segundo cultivo oleaginoso más importante en la Argentina. Desde hace varios años, se vienen realizando diferentes estudios agronómicos, fisiológicos y genéticos con ... -
Implicancias del estrés hídrico en la calidad forrajera de Cenchrus Ciliaris l. y su relación con la anatomía foliar y el metabolismo de la lignina
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2022-10-03)Cenchrus ciliaris L. es una importante gramínea forrajera distribuida en regiones áridas y semiáridas del mundo para la alimentación de ganado vacuno. En Argentina, esta especie ha sido introducida en el noroeste del país. ... -
Influence of Soil Water Status on Arbuscular Mycorrhizas in Three Perennial Grasses in Central Argentina
(Finnish Zoological and Botanical Publishing Board, 2008-12)In this field study, we determined the effects of water stress, rainfed or irrigated conditions on the arbuscular mycorrhizal fungal (AMF) root colonization in the late-seral Stipa clarazii, the earlier-seral S. tenuis and ... -
Soil Phosphorus Concentration under the Canopy of Perennial Grasses of Different Successional Stages Exposed to Water Stress
(Taylor and Francis, 2008-10)In this field study, the effects of water‐stress, rainfed, or irrigated conditions on soil phosphorus (P) concentration under the canopy of the native grasses of semi‐arid Argentina (late seral Stipa clarazii Ball., early ... -
Transcriptomic Analysis Reveals a Differential Gene Expression Profile Between Two Sunflower Inbred Lines with Different Ability to Tolerate Water Stress
(Springer, 2020-01)Although sunflower (Helianthus annuus L.) is categorized as a medium drought-sensitive crop, in a changing climate scenario and/or with the onset of early droughts, the crop may be affected by water stress. This study ...
